Discovering the hidden benefits of cognitive interviewing in two languages: The first phase of a validation study of the Integrated Palliative care Outcome Scale

Abstract

Cognitive interviewing proved valuable to increase face and content validity of the questionnaire. The concurrent approach in two languages - to our knowledge the first such approach in palliative care - benefited the refinement. Psychometric validation of the refined Integrated Palliative care Outcome Scale is now underway.
